# SUPPLEMENTARY INFORMATION:

Custom Feed Services Corp., 2100 N. 13th St., Norfolk, NE 68701, has requested that FDA withdraw approval of NADA 121-200 for Tylosin 10 Premix (tylosin), NADA 129-159 for TYLAN 40 Sulfa-G (tylosin and sulfamethazine), and NADA 137-484 for Swine Guard-BN (pyrantel).

                    In a final rule published elsewhere in this issue of the                     **Federal Register**                    , FDA is amending the animal drug regulations to reflect the withdrawal of approval of these NADAs.
